Benefits of technology

[0029] wherein in use said source of said fluid under pressure flexes said diaphragm causing it to align with said contoured surface and thereby prevent flow of fluid through said valve conduit.
[0044] wherein said generally concave inner surface is shaped such that upon flexure of said diaphragm under the influence of fluid under pressure, said flexed diaphragm will make contact with and seal against said concave inner surface to thereby prevent flow of fluid through either said valve inlet or said valve outlet, or both.

Problems solved by technology

Although not all cases of Legionnaires' disease are severe, it can be fatal.

Embodiment Construction

[0057] Illustrated in FIGS. 1 and 2 there is shown a cross-section view of an evaporative air conditioner drain valve 10 which is constructed so as to be inserted into a floor 12 of a fluid containment reservoir of water in the form of a sump 38 (FIG. 3) which is used in the evaporative air conditioning process as will be described further below with reference to schematic FIG. 3.

[0058]FIG. 1 shows the valve 10 in an open position while FIG. 2 shows the valve 10 in a closed position.

[0059] The valve 10 has a generally circular valve body when viewed from a top view. The valve 10 includes a base portion in the form of base 4 and a cap portion in the form of cap 1. When viewed in top view, the base 4 has a generally concave surface in the form of annular seat 14. The valve 10 also has a valve outlet in the form of discharge outlet 16 to which a fluid release outlet such as dump pipe 48 (FIG. 3) can be connected for conducting water away from the sump 38 to a storm water drain or oth...

Abstract

A fluid release system is disclosed comprising an apparatus that utilises fluid under pressure in operation. The system also includes a control means adapted to control the supply of fluid under pressure to the apparatus and a fluid containment reservoir adapted to contain fluid utilised by the apparatus in operation. A fluid release outlet is provided in the fluid containment reservoir, the fluid release outlet being adapted to allow fluid to be released from the fluid containment reservoir. A valve operatively associated with the fluid release outlet, is provided which is adapted to be opened to allow flow of the fluid from the fluid containment reservoir to the fluid release outlet. A pressure operated valve closure means to close the valve in use is also provided. In use, the pressure operated valve closure means is adapted to be connected to a source of the fluid under pressure in operation of the apparatus to thereby close the valve. A valve for use in the fluid release system is also disclosed.

Description

FIELD OF THE INVENTION [0001] The invention relates to a fluid release system and to a valve that can be used in a fluid release system. More particularly, the present invention relates to a fluid release system such as a drainage system for a vessel containing fluids under pressure such as in an evaporative air conditioner. BACKGROUND OF THE INVENTION [0002] In particular applications, it is desirable for vessels in one operating state to contain fluids and in another operating state for the fluids to be removed or released from the vessel. One known solution to remove fluids in liquid form from vessels is to allow the vessels to be drained of the liquids contained within the vessel by an operator having to manually actuate a drainage valve. [0003] An example of a vessel which contains / utilises liquids in one operating state while requiring that they be removed in another operating state is an evaporative air conditioner. Evaporative air conditioners, which are also known in the ar...
